+# Tutorial
+This part, we look into the code. Take [backpack.yaml](/example/backpack.yaml) for example. 
+## Apperence
+```yaml
+id: backpack
+type: drop
+block: minecraft:barrel
+item:
+  id: minecraft:leather_chestplate
+  tag: 
+    display:
+      Name: {text: Backpack, italic: false}
+    Unbreakable: true
+    HideFlags: 127
+    AttributeModifiers: []
+    CustomModelData: 54621503
+```
+* `id` is for tikc mcfunction to recongnize what GUI block it is.
+* `type` is `drop` or `spawn_egg`. `drop` means that it summon GUI item when you drop the block on the ground; `spawn_egg` means the item is a spawn_egg.
+* `item` is the item of the GUI block, it's in Minecraft item NBT format. The item also show at the buttom of the GUI block when it turn into the GUI block. You can make texture of it by adding `CustomModelData` tag.
+## Events
+```yaml
+load: 'say load'
+destroy: 'say destroy'
+tick: 'say tick'
+```
+* `load` is run when the GUI block is spawn and the item (or area cloud effect if the type is `spawn_egg`) haven't be killed, it run by the item. The GUI block have a block (barrel in this example) and an entity (always item_frame). The entity have a tag called `egset`, you can use it to do the data load, for example, you can copy the display name of the item to the custom name of the entity by `/data` command.
+    ```yaml
+    load: 'data modify entity @e[tag=egset,limit=1] CustomName set from entity @s Item.tag.display.Name'
+    ``` 
+    If you want load the data of the block use `block ~ ~ ~` to locate the target.
+    ```yaml
+    load: 'data modify block ~ ~ ~ CustomName set from entity @s Item.tag.display.Name'
+    ``` 
+* `destroy` is run when the item_frame is summon and the GUI block is haven't be killed. The drop also have a tag `egset`, you can use `entity @e[tag=egset,type=ite,sort=nearest,limit=1]` to locate it. You can use `block ~ ~ ~` to locate the block.
+* `tick` is run by the item_frame every tick.
+## Slot Behavior
+```yaml
+slot:
+  0..8,18..25:
+    type: label
+    item:
+      id: minecraft:black_stained_glass_pane
+  26:
+    type: label
+    item:
+      id: barrier
+      tag:
+        display:
+            Name: {text: Close, color: red, italic: false}
+    click: 'say click'
+  9..17:
+    type: drop
+    cond: if
+    data: 'eg'
+```
+`slot` let you design the behavor of each slot. The key `0..8,18..25` means the slot 0~8 and 18~25 have the same behavior.  
+The behavor have 3 type, `drop`, `label`, `n_left`
+### drop
+Drop behavior have 4 condition, `always`, `never`, `if`, `unless`.
+* `always` means it always drop the item in that slot.
+* `never` means it never drop, you can see it as do nothing.
+* `if` means if it meet the specific condition, it drops, for example
+    ```yaml
+    9..17:
+        type: drop
+        cond: if
+        data: 'display'
+    ```
+    The item drop if it has `display` tag, it may be the dyed item, renamed item ... 
+    ```yaml
+    9..17:
